\VILLIAM HENRY LLOYD, OF HOUTZDALE, PENNSYLVANIA.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 579,757, dated March 30, 1897.

Application filed July 14, 1896- Serial No. 599,162. (No model.)

To all whom' it'may concern:

I Be it known that LWILLIAM HENRY LLOYD, a citizen of the United States, residing at Houtzdale, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Wagon- Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in wagon-brakes, and more particularly to that class of brakes which are applied automatically when the vehicle is traveling downgrade and which will be automatically. released when on a plane or going up an incline.

The object is to provide a simple, cheap, and durable device of'this kind; and to this end the novelty consists in the construction, combination, and arrangement of the same, as will be hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same figures of reference indicate the same parts of the invention.

Figure 1 is a perspective view of a vehicle to which my improved brake has been applied. Fig. 2 is an enlarged top plan view of the rear end of the tongue, showing the manner of connecting it to the brake mechanism; and Fig. 3 is a sectional side elevation of the same.

1 is the wagon-body, and 2 the tongue of an ordinary team.

3 3 are the tongue-hounds, and 5 the doubletree. The rear end of the tongue 2 is formed with parallel sides, which slide into the parallel jaws of the hounds. A bolt 8 passes through the forward ends of the hounds and through an oblong hole 9 in the tongue. This construction permits a longitudinal movement of the tongue in the hounds. The doubletree 5 is pivoted to the rear end of the tongue forward of the oblong hole 9 by a vertical bolt 10.

12 is a U-shaped yoke-bracket secured to both hounds and extending a sufficient distance below them to receive a bolt 13, on which is fulcrumed a lever 14, the upper end 15 of which is pivoted in a vertical slot 16 in the rear end by a bolt 11 of the tongue 4, and to the lower arm 17 of said lever is pivoted one end of a connecting-rod 18, the other end of which is pivoted to a spring-crank 19, integral with the crank-shaft 20, secured in bearing-boxes 21 21, secured to the under side of the floor of the wagon. The outer ends of this crank-shaft 20 are formed with brakecranks 22, having arms 23, on which are pivoted the usual brake-shoes 2 1.

An auxiliary crank 25 is secured to the crank-shaft 20, and its outer end is provided with a bolt 26, which engages an integral link 27 on the rear end of the connecting-rod 28, the forward end of which is pivoted to the brake-lever 29, fulcrumed on a stud 30, secured to the side of the wagon, and, as will be seen, the brake can be applied at will by hand.

When the wagon is traveling down an incline, the body runs forward on the tongue. This causes the bolt 8 to slide forward in the oblong hole 9. The rear end of the tongue presses against the upper arm 15 of the lever 14, throwing the lower arm 17 forward, drawing the rod 18 with it, which turns the crankshaft 20 and applies the brake-shoes. "When the tongue is drawn forward again, the bolt 11 draws the upper end of the lever 14 forward and releases thebrake.

The lever 14, its rod 18, and the crank-shaft may be operated to automatically apply and release the brake without interfering with the hand-lever, as the bolt 26 on the auxiliary crank 25 slides forward in the link 27 on the rod 28 without operating it or the hand-lever.

31 is a short chain, one end of which is per manently secured to the dashboard of the wagon, and its free end is provided with a locking-pin 32, which when not in use is insorted in a staple 33, located in any convenient place on the dashboard,as shown. Whenever it is desirable for any reason to prevent the tongue-brake from operating, said pin 32 is inserted through a hole 34 in the hounds, passing through a similar hole 36 in the end of the tongue, which is alined with the hole in the hounds when the tongue is drawn forward and the brake-shoes released. This looks the tongue in the hounds and prevents the longitudinal movement of the tongue, and consequently the automatic application of the brake. In this case when it is desired to apply the hand-brake there is sufficient elasticity or spring in the crank 1.9 to permit the hand-lever, its rod, and the auxiliary crank 25 to operate to apply the brake-shoes.

Although I have specifically described the construction and relative arrangement of the several elements of my invention, I do not desire to be confined to the same, vas such changes or modifications may be made as clearly fall within the scope of my invention without departing from the spirit thereof.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s

The tongue 2 formed with an oblong hole 6, circular hole 36 and the vertical slot 16, the hounds 3 3, the transverse bolt 8 passing through the hounds and through the oblong hole 6 in the tongue, the semicircular bracket 1S, and the detachable pin 32, substantially 30 as shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

WILLIAM HENRY LLOYD.
